  • Benfield and Geoscience Australia intend to collaborate to improve their respective understanding of risks from natural hazards in Australia. The aim of this project is to exchange ideas, data and models in order to support the respective groups risk modeling expertise.

  • This the top-level collection record for all of Geoscience Australia's public vocabularies. The vocabularies are all formulated using the SKOS (Simple Knowledge Organization System) information model and delivered both as machine-readable Resource Description Framework (RDF) data and also as HTML web pages. Each vocabulary is delivered individually as RDF & HTML data and all vocabularies are linked to from both GA's vocabularies index static web page and also from the Australian National Data Service (ANDS)'s Research Vocabularies Australia (RVA) portal. All vocabularies, collections of concepts within vocabularies and individual concepts are identified with URI persistent identifiers of the form: http://pid.geoscience.gov.au/def/voc/ga/{VOCABULARY-KEY}/{COLLECTION-OR-CONCEPT-NAME} This means that you can access all the information about a vocabulary, a collection or a concept directly by entering that URI into your web browser.

  • This collection contains Earth Observations from space created by Geoscience Australia. This collection specifically is focused on data and derived data from the European Commission's Copernicus Programme. Example products include: Sentinel-1-CSAR-SLC, Sentinel-2-MSI-L1C, Sentinel-3-OLCI etc.

  • In May 2013, Geoscience Australia (GA) and the Australian Institute of Marine Science (AIMS) undertook a collaborative seabed mapping survey (GA0340/ SOL5754) on the Leveque Shelf, a distinct geological province within the Browse Basin, offshore Western Australia. The purpose of the survey was to acquire geophysical and biophysical data on seabed environments over a previously identified potential CO2 injection site to better understand the overlying seabed habitats and to assess potential for fluid migration to the seabed. Mapping and sampling was undertaken across six areas using multibeam and single beam echosounders, sub-bottom profilers, sidescan sonar, underwater towed-video, gas sensors, water column profiler, grab samplers, and vibrocorer. Over 1070 km2 of seabed and water column was mapped using the multibeam and single beam echosounder, in water depths ranging between 40 and 120 m. The sub-surface was investigated using the multichannel and the parametric sub-bottom profilers along lines totalling 730 km and 1547 km in length respectively. Specific seabed features were investigated over 44 line km using the sidescan sonar and physically and sampled at 58 stations. Integration of this newly acquired data with existing seismic data will provide new insights into the geology of the Leveque Shelf. This work will contribute to the Australian Government's National CO2 Infrastructure Plan (NCIP) by providing key seabed environmental and geological data to better inform the assessment of the CO2 storage potential in this area of the Browse Basin. This data package brings together a suite of datasets which describe the seabed environments and shallow geology of the Leveque Shelf, Browse Basin.

  • Geoscience Australia is the custodian of the most comprehensive publicly available Australian airborne magnetic, gamma-ray, seismic, electromagnetic and gravity data sets. The airborne geophysics data set contains approximately 34 million line kilometres of data, which, at current prices, would cost approximately $197 million to acquire. The gravity data set contains more than 1.57 million reliable onshore stations gathered during more than 1800 surveys. The collection also includes a large number of seismic surveys from Australia's offshore basins. The onshore component of this data set was previously approved for RDSI for 8 TB. This proposal extends the collection to 150TB. The data types and access methods for the Offshore and Onshore data are identical Certain holdings are additionally hosted at the NCI (see downloads)

  • This collection contains Earth Observations from space created by Geoscience Australia. This collection specifically is focused on derived or value-added products. Example products include: Fractional Cover (FC), Australian Geographic Reference Image (AGRI), and InterTidal Extents Model (ITEM) etc.

  • Archive of the data and outputs from the Assessment of Tropical Cyclone Risk in the Pacific Region project. See GA record 76213.

  • Descriptions of and measurements from field sites and samples from geological (including regolith) surveys. <b>Value: </b>Used to constrained surface geology, important in resource exploration and understanding physical environment. <b>Scope: </b>Mapping surveys mainly in Australia, but also in Antarctica, Oceania and south-east Asia.

  • This collection includes Global Navigation Satellite System (GNSS) observations from short-term occupations at multiple locations across Australia and its external territories, including the Australian Antarctic Territory. <b>Value: </b> The datasets within this collection are available to support a myriad of scientific applications, including research into the crustal deformation of the Australian continent. <b>Scope: </b> Data from selected areas of interest across Australia and its external territories, including the Australian Antarctic Territory. Over time there has been a focus on areas with increased risk of seismic activity or areas with observed natural or anthropogenic deformation. <b>Access: </b> The datasets within this collection are currently stored offline, to access please send a request to gnss@ga.gov.au
